Question about Mitsubishi WS-55513 55" Rear Projection HDTV
We have the famous flashing green light. I am trying to get the dm module out and I am not sure what all needs to be removed to get it out. There seems to be something in side the silver case in the back that is holding it onto the bottom and I can't get enough clearance on top to get it off.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Two choices =
1) Replace DM MODULE. 650.00 is right.
2) Rebuild DM MODULE. Done right = a little less than Mits.
Caution: High degree of skill needed and ask about warranty
in either choice.Rebuilds usually cover only parts installed,
not complete module.If you do the research on repair,you
will find pin push reset does not work,in most cases....T.

The four cap replacement in DM module repair is simplistic
and incomplete, as you found out. ALL defective DM modules
have bad SMC's ( small "top hat" caps) AKA surface-mount
capacitors that can be changed only by the most highly skilled
bench techs. We used to change out hundreds years ago in
camcorder circuit board repair.DM board repair is a much more
accessible,thus more "do-able". For more info.............T.

Picture of bad caps
The DM board is the one with the digital connectors on the back panel. If you already have it appart, you may as well check the caps on all of the boards. The caps that go bad are typically Jamicon brand caps in 1000 uF and 330 uF values. There are also a couple of 3300 uF caps in the PS that cause problems.
